The present preferred embodiment of the invention, referring preliminarily to its general features, provides va stereotype plate making machine which comprises casting mechanism, plate trimming mechanism and an intermediary plate carrier or conveyor, all operating automatically and having novel constructions, parts and features as hereinafter described.

The plate after casting is left in the drag by the opening or separation of the core and drag, the automatic plate carrier engaging the plate in the drag land delivering it into the trimming mechanism and automatically starting the trmming mechanism into operation, the trimming mechanism in turn automatically delivering the finished plate therefrom. Y

As herewith preferably embodied,the casting chamber is vertically disposed, the automatic carrier engaging the plate and supporting it by its bottom curved edge, the plate carrier turning while carrying the plater and Vdelivering the plate into the trimming mechanism in horizontal position, while resting on its straight edges. As embodied, the core swings away from casting position on a vertically disposed axis and is automatically operated in timed relation with the other operations of the machine.

The concave casting member, or drag, as it is usually styled, is vertically disposed, as embodied, and is preferably fixedin position although it could ybe, swung to horirental4 position for changing matrix sheets. The drag is also provided with an automatically receding back and with spring operated matrix-holding clamps or jaws, mounted on the recedingvbaclr portion of the drag, whereby the matrix sheet is stripped from the ,east gaat@ essentially While te@ soy plate is in position Within the drag, prepara` tory tothe plate being automatically taken away by the plate carrier.

Other' features of the invention will be initially set fer-th in connection with the felloiving detailed description of the present preferred embodiment of the invention, but it Will be understood that both the preceding general description and following detailed description are exemplary and explanatory and are not restrictive of the inven-tion.

Referring now in detail to the embodiment of theV inventiom illustrated by Way of example in the accompanying drawings, a casting couple isV shown consistingof a vertically disposed drag er concave castinginember 1, which is preferably in fixed. position upon the general frame of the machine. Cooperating there-With is the convex casting member or core 3, which is movable to- Ward and from casting position, and as shown. herein (Figs. 1, 2 and 6), swings. to and from casting position about a vertically disposed axis. The core 3 is provided With hinge members` 4, 5, and 6, the member 4 resting upon a corresponding hinge member 7 formed. ony the frame or extending out from the stationary drag, and hinge member 6 resting upon a supporting member 8 formed on the machine frame. The open or non-casting position of the core 3 is shown in broken lines in Fig. 1.

The drag and core will be provided with the usual spaces for the cooling Water, shown herein. only conventionally., and suitable piping in connection therewithl for supplying the Water Will be provided of any convenient or adequate form, the same being omitted from the drawings. i.

The receding back of the drag, which is the portion thereof located just behind the matrix sheet, and the cooperating automatic stripping clamps for the matrix sheet are shown only generally so far as concerns their specific structure., but they are constructed and arrL nged in the machine to operate automatically as. the core swings aivay from the drag and preparatory to the plate carrier taking the plate out of the drag. rFhe receding back 12 shovvn generally in; Figs. 3, 7 and 8, and the spring matrix clamps and 14 are shownin casting position in Fig. 7 and are shown inmatrix stripping positiony in Fig. 8, the4 matrix being marlred by reference numeral. 15, and the plate by w. The detailed construction of the receding back and the automatically voperating matrix clamps maybe substantially the same as is shown and described in copending application Ser. No. 408,203 of Albert A. Henzi, filed September 4, 1920.

Referring now in detail to the actuating and controlling means for the mechanism al;-

ready described, a driving shaft 16 is driven from any suitable source of power, and is provided With a clutch 17 which may be either manually or automatically operated. The shaft 16 is mountedk in bearings 18, 19 and 20 in the machine frame. Fixed on shaft 16, (Figs. 3 and 4) is a Worm 21, with which meshes a Worm Wheel 22. VVoi-m Wheel 22 is fixed on a shaft 23, and fixed also on shaft 23 is a cam cylinder 24, which governs and times the operation of the dif'- ferent parts of the machines asv will be later described.

Referring nonv in detail to the actuating mechanism for swinging the core to and from casting position and for ope-rating the receding back 12 of the drag, there is fixed on shaft 16 a beveled gear Wheel 30, which meshes With tivo gear vvheels 31 and 32, mounted loosely on a shaft 33, which shaft is journaled in bearings 34` and 3.5' in the machine frame. Between the beveled gears 31 and 32 is a clutch member 36, splined to but slidable along shaft 33 into engagement alternatively with either bevel gear 31 or 32, to drive the shaft 33 in one direction or theother.' The clutch 36 also has a central position, out of mesh with beth pinion-s 31 and 32, to provide the necessary dwells for the core and the receding back of the drag.

rlhe clutch member 36, as embodied, automatically operated by a yoke lever 33 engaging in an annu-lar groove 39 in the clutch member 36. Lever 33 is pivotedat 40 on the machine frame. A pivoted link 41 connects the lever 40 With a lever 42, which lever is pivoted at 43 upon the machine frame. rlhe other end of leve-r 43 cooperates with :i cam groove 44 formed inv the cam cylinder 24;. By this means the operation of the core 3 and of the receding bacls:

12 is properly timed. in connection with the other functions of the machine.

The further connections and controls, as embodied, for the mechanism just mentioned comprise a beveled gear Wheel 46 fixed on shaft 33, and meshing with a bevel gear Wheel 47, which is fixed on a vertically disposed shaft 48, and supported on a bearing 40 on the machine frame. Shaft 43 is also provided with an enlarged hub or sleeve 50 Within the bearing 49. The hinges 4, 5 and 6 are fixed toz the. shaft 4.8 vby suitable means, sucli as pins or clamping bolts 51, 52 and 53 respectively.

Referring now to. the additional actuating means for the recedingk back 12, a bevel gear Wheel 60 is fixed on shaft 43, and meshing therewith is a bevel gear 61,'xed on a shaft 62, Which is journaled in bearings 63 and 64 on the machine frame. On they opposite end of shaft 624 is a bevel gear 65, With Which meshes a bevel gear 66, which is fixed on ashaft'67, journaled in bearings Cil G8, 69 and 70 formed on the machine traine, that is, in thisinstance, on the tired part ot the vertically disposed drag. Fixed on shaft 67 'is an eccentric 71, working within an eccentric strap 72, which is pivotally connected at 73 to the movable back 12 of the drag. The matriz; clamps 13 and 1d operate in the usual manner, being pressed home lo the casting position oit Fig. 7 by the core, and automatically springing out-to the matrix stripping position ot Fig. 8 when the core swings away vfrom casting position. The matrix clamps -torni the straight edges ot the casting chamber in the usual manner. In the preferred `form of the invention, the plate is cast with a tail or waste portion at each end thereof. 1n the bottom end, there are preferably three recesses fw, y, and with which the plate carrier engages to taire the plate out of the drag. The recesses te and e are formed in the cast plate by projections on the core 3. The recess y is -formed in the cast plate by a projection 10 (Fig. 3), which is mounted on thereceding back and thus withdraws from recess y when the haelt 12 rccedes in the matrix stripping operation. The end rings for the matrix sheet are indicated. as 9 and 11.

Referring now in detail to the embodied forni of plate carrier, this carrier'as already stated, is adapted to engage the cast plate as it stands in casting position in the vertically disposed drag. to engage` it on its lower curved edge, to remove it trom the drag supported on said edge, and to rotate it as it is so moved to a horizontal position wherein it rests on the carrier upon its straight edges, and 'from this position to dem liver it into the jjilate trinnninry mechanism. its embodied, 1, 2, S, o and 9), the plate carrier comprises a part reciprocable to and fro along a horizontally disposed guideway and a part pivotally mounted thereon and having swinging movement thereon to handle the plate in the manner described. In this embodiment, the swinging part 8O is provided with a semi-circular member 81, which is preferably provided centrally with a projecting lug 82, adapted to lit into the projection y, formed in the bottom of the cast plate a; (Figs. 1 and 11). .ttt either side the supporting member S1 is provided with projections 83 and 94tadapted to fit into recesses fw and e formed in the cast plate a (Fig. 11). lust within the projections SS and 84; and adapted to tit closely against the inner curved surface ot the semi-cylindrical plate fr are projections or seats 85 and 86. Projecting vertically trom the supporting part 8l for the curved end ot the plate is the part of thecarrier 8f) which is adapted to support the straight edges of the plate. Said part is provided with two arms 87 and 88, provided with seats 89 and 90 tor the straight edges ot the plate, which extend well along the straight edges to hold the plate firmly in its seat during the turning of the plate on its carrier. j

The portion ot the plate carrier just described is pivotally mounted on the other portion ot' the carrier, already referred to as rcciprocably traveling along gnideways on the trame, and which is reciprocable to and 'fro between the casting mechanism and the trimming mechanism, or a place of delivery for the cast plate when the trimming mechanism is not employed. As embodied (Figs. 1, 3, 5, 6 and 9), the carrier 8O is provided with arms 91 and 92, projecting outwardly and downwardly therefrom and fixed to a shaft 93, which shaft is journaled in brackets 941- and 95 formed on the reciprocably traveling body 96 of the plate carrier. This body 96 of the plate carrier is provided with downwardly projecting parts 97 and 98, formed on their under and inner sides to lit upon and slide along parallel, horizontallydisposed guideways 99 and 100 formed on the machine frame.

The means for rotating or swinging the plate carrier between plate receiving and plate delivering position as embodied, coniprises a sleeve 101, fined cenfrally to shatt 98 and dovmwardly extending from this sleeve 101'are arms 102 and 1023. ,firm 10:@ has a pin lO-'i projecting horizontally thereH 'from into a. cam way or gnideway 195 formed in the machine traine. rm 109 hasfa similar pin 106 projecting into a similar guideway 10.7 for: red in the nnichine iframe. T he shape of the camways 105 and 10'(y is such to give the required more .ment to the plate carrier (as best indicated in Fig. 10) to turn the plate Atrom the vertical receiving position to the horizontal delivery position.

The means ttor reciprocating tl e cast plate carrier to and 't'ro between plate receiving and plate delivering posicion as embodied comprises a. stra-ight raclr or gear 115 extending horizontally along the machine trame beneath the plate carrier. donrnaled in the bottom part ot the body 96 ot the plate carrier is av shaft 11G (Fig 35 and 5) and keyed thereto to rotate ther with is a geared pinion 11'?, within a housme', and wiich meshes rwith the straight r 115, (lig. 12). w

Fixed also on shalt 116 is a worm wheel 118, the worm wheel 119 being located witln in a housing 119, Yformed on the plate carrier. Worm wheel 1155 meshes with a worin 190, which is mounted upon a floating shaft lland connected thereto by a spline '122, whereby the shaft and worm will rota-te together, but the worm will slide freely along the shaft. Shaft 121 one end thereof is provided with bearings 123 and 124, and fixed to the shaft between said bearings is a gear wheel 125. Meshing with gear wheel 125 is .a gear wheel 1126, fixed on a shaft 127, which shaft is journaled at 128,129,130 `and 131 in the machine 'rrame.

Mounted loosely on shaft 127 are two bevel gf-iary wheels 132 and 133, both said gear wheels meshing `with a bevel pinion 134. Pinion 134 is yfixed on a. shaitt135, journaled at 136 and 1.37 in the machine frame. F ixed also on shaft 135 is a bevel gear 138, and meshing therewith is a bevel gear 139, fixed on a shaft 140, which shaft is ournaled in bearing 141 .and 142 upon the machine frame. `Fixed to shaft 140 is a bevel gear wheel 143, with which meshes a bevel gear wheel 144, which is fixed on the shaft 16.v

In the embodied form of means for ref versing and controlling the travel of the plate carrier in harmony with the opera* tions of the other mechanisms, a clutch member 154 is mounted upon shaft 127 to rotate therewith, but being slidable therealong to pass alternatively into engagement with either of the pinions 132 or 133 to reverse the direction of the drive of shaft 127 by shaft 135, or to stop in intermedia-te position, out of mesh with both pinions, to provide the dwells for the plate carrier. Clutch member 154 :is provided with an annular groove 155, which is engaged by a yolred lever 156 pivoted at 157 on the machine frame.

Pivotally connected to the other end of lever 156 is a rod 153, the other end of the rod 158 being pivotally connected at 159 to a lever 160, which lever is pivotally'supported at 161 upon the machine frame. At its opposite end, lever 160 is pivotally connected to a rod 162, ytheother end of the rod being pivotally connected to a lever 163, which lever is pivotallysupported at 164 upon the machine frame. Lever 163 has its other end cooperating with a groove cam 165 formed in the cam drum 24.

The manner of operation of the lmechanism just described is substantially as follows :-v f

rIyhe casting mechanism may be regarded as in the closed or casting position just subsequent to the casting of the plate. Cam groove 44 in drum 24 operates lever 42 to drive shaft 33 in the proper direction, from shaft 16, and shaft 48 is partially rotated, thereby lswinging the core 3 to the open or broken line position of Fig. 1, and at ythe same time the back 12 of the drag is mover from the position of Fig. 7 to that of Fig. 3, and the matrix 15 is stripped from the just cast plate Clutch 36 will then be moved to neutral position and will remain there .until the plate carrier taking away the cast plate is clear, when it will be moved linto engagement with the other oi the two `projections 83 and 84 pass into the recesses v fw and e, the straight edges of the plate a: vresting against the seats 39 and 90. The 4projections 82, 83 and 34 are slightly beveled at their forward end and are just thick enough to ease the plate from its seat in the drag, so that it will rest irmly upon the plate Acarrier and will move backwardly therewith. n I

The plate carrier then moves backwardly carry-ing the plate toward the trimming mechanism or place of delivery. During this movement the pins 104 and 106 are rimning in the cam grooves 105 and 107, res-pectively, and because of the shape of these grooves, the plate carrier is given a quarte-r tnrn about shaft 93 from the broken line position of Figs. 3 and 10, to the full line position of said figures, and the plate is then inhorizontal position to be delivered into the finishing mechanism, as shown in Fig. 2. On the reverse movement of travel of the plate carrier, the plate supporting member 30 moves in the opposite direction as indicated by the arrows in Fig. 10.

The operation of the driving and controlling mechanism yduring the foregoing function of the plate carrier is substantially as follows: n

Shaft 140 and shaft 135 are driven from shaft 16, as already described, and lever 163 will throw clutch 154 to drive shaft 127 in a given direction. This will drive shaft 121 in a corresponding direction and worm 120 will drive worm wheel 113, rotating shaft 116, and pinion 117 will roll along rack 115, traveling the plate carrier along the guides 99 'and 100 in the desired direction. Lever 163 will then be moved to throw the clutch 154 into neutral position for the desired kperiod of dwell, and will then throw it into engagement with the other of the two bevel gears 132 and 133, to effect the travel of the plate carrier into reverse direction and will provide the necessary dwell at the opposite end of its travel.

ln the embodied form of plate trimming mechanism, a machine is shown of the general type or kind illustrated and Vdescribed in United States Patent No. 1,126,741 to Evensen, dated February 2, 1915. This plate trimming machine is adapted to receive the plate ruiming on its straight edges into the interior of a cylinder, the plate `being clamped therewitliin, and given one complete rotation during` which the ends of the plate are trimmed and also the interior ribsthereot. The plate is then slidL on its straight edges out oit the trinnning mechanism, traveling in the same direction in which it entered the trimming mechanism along a trackway 188, being sent forward to a. place oit delivery or otherwise disposed of. It will be understood that so 'far as concerns certain features et the invention, the plate may be delivered directly from the casting mechanism without being sent into the trimming machine by the plate carrier.

In the embodied form ot means yfor delivering the plate to the trimming means, a reciprocating bar 180 is mounted in. the upper part of the trimming machine 181, the bar being provided with a straight. gear rack 182, with which meshes a gear wheel 183, mounted on a shaft 1841-. Fixed also on Shaft 184 is a gear wheel 185, which meshes with a reciprocating geared sector 186, which is reeiprocated by any suitable driving mechanism. Bar 183 has pivoted to the end thereof a depending finger 187 which engages the plate on the plate carrier, as shown in Fic'. 2 and pushes it into the trimming mechanism. Suitable means will be employed to prevent the linger 187 deacing plate fc, as its end may be covered with ln'ctectivematerial, such as sott leather or any other suitable material, it found neeessa-ry. Any convenient mechanism could be employe-d for raising and lowering the iinger it desired.

The conveyor arm 180 for the trimming mechanism may be started into operation from the casting mechanism by any suitable means. As shown a trip lever 189 for a clutch Jfor the conveyor kis operated by the plate carrier, or a cam control of any suitable form might be arranged on one of the shafts of the casting mechanism. The trimming mechansm may also be started on its rotary trimming movement by any suitable automatically' operating mechanism, which may be like that already described for the conveyor. As shown, an arm 190, corresponding to the starting arm 58 in the Patent No. 1,126,741 referred to, is engaged by an arm 191 extending outwardly from the bar 180. An automatic conveyor 192 et anyk known or adequate Jform may be employed to automatically remove the trimmed late a; from the ytrimming mechanism.

In 13 is shown diagrammatically an automatic hot metal supply tor the casting mechanism. The pump 200 has its lever 201 connected by a pivotedk link 202 to a camactuated lever 203, which is pivotally supported at 204i. Lever 203 is operated by a cam 205 on shaft 16. If clutch 1'7 is left in, the machine will run continuously, casting and re-casting from a single matrix.

It only a. single cast plate troni a particular matrix is required, the clutch 17 may be provided with any standard or adequate form of throw-out for one cycle of the machine, or the clutch may be operated manually. In Fig. 14 there is shown a form of throw-out which will stop the machine automatically after each plate is cast, or will cause the continuous operation ot' the machine.

ln Fig. 1&1 the control lever 206 for clutch 17 is held in driving position by a detent latch 207, which ispivoted at 208, and has its nose beveled so that the lever 206 will pass underneath and be held when the clutch is thrown into driving position. The tail of lever 207 is pivoted at 216 to a connecting link 209, the other end of the link being pivoted at 210 to a cam lever 211.

Cam lever 211 is pivoted at 212 and is actuated by a cam 213 on cam roll 24. When lever 211 is tripped by cam 213, lever 206 is released, and the spring of clutch 17 will throw out the clutch. When the clutch is thrown in rby hand, detent 207 will auto matically hold it until cam 213 releases it.

Means are provided whereby, if continuous operation is desired, as when a number of plates are cast from one matrix, lever'206 will be held in operative position. As shown a detent 2111 is pivoted on support 208, but tree from detent 207. This detent 214C is provided with a finger piece 215. When single casts are made, detent 214 will be swung back over its center to idle posi# tion. When successive casts from one matriX are to be made, and detent 214: isin the full line position of Fig. 14, the automatic operation of detent 207 will have no effect on lever 206.

The invention in its broader aspects is not Vlimited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sac rillcing its chiel:l advantages.
